SAFETY-RELATED COMPONENT WARNING!!

COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH

MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS

LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE

COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS

APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS

PUBLISHED BY SONY.

After correcting the original service problem, perform the

following safety checks before releasing the set to the customer:

Check the antenna terminals, metal trim, “metallized” knobs, screws,

and all other exposed metal parts for AC leakage. Check leakage as

described below.

LEAKAGE

The AC leakage from any exposed metal part to earth ground and

from all exposed metal parts to any exposed metal part having a

return to chassis, must not exceed 0.5 mA (500 microamperes).

Leakage current can be measured by any one of three methods.

1. A commercial leakage tester, such as the Simpson 229 or RCA

WT-540A. Follow the manufacturers’ instructions to use these

instruments.

2. A battery-operated AC milliammeter. The Data Precision 245

digital multimeter is suitable for this job.

3. Measuring the voltage drop across a resistor by means of a

VOM or battery-operated AC voltmeter. The “limit” indication

is 0.75 V, so analog meters must have an accurate low-voltage

scale. The Simpson 250 and Sanwa SH-63Trd are examples of

a passive VOM that is suitable. Nearly all battery operated

digital multimeters that have a 2V AC range are suitable. (See

Fig. A)

* Procedure:

While depressing the TUNER and the VIDEO buttons

simultaneously, press the power [?/1] button to turn on the main

power. The model name, destination and the software version are

displayed.

FLUORESCENT INDICATOR TUBE TEST MODE

* All fluorescent segments are tested. When this test is activated,

all segments turn on at the same time, then each segment turns on

one after another.

* Procedure:

While depressing the TV/SAT and the CD buttons simultaneously,

press the power [?/1] button to turn on the main power.

1. All segments turn on.

SET UP, SOUND FIELD, BASS BOOST and MUTING LED

turn on.

2. Press the VIDEO button, confirm display
